This study empirically examines the responses of trade margins to a battery of technical barriers to trade (TBT) and explores the mechanism, drivers and speed of adjustment. It uses a highly-disaggregated transaction-level dataset of mango-exporting firms from Pakistan and exploits a quasi-natural experiment in the identification strategy. It finds that, following the application of TBT measures, exports increased along the intensive margins. The process of adjustment took around four years, and larger quantities as well as higher prices drive this effect. Moreover, firms shrink their client base in destination markets but ship large quantities to a few big retailers. 相似文献

Based on the hypothesis that Egyptian farmers maximise economic profits, the multiproduct translog profit function is used to estimate input demand and output supply functions for corn, rice, and cotton crops grown in Egypt's Nile delta. Elasticity estimates indicate a generally high degree of price responsiveness. The estimates are used to evaluate Egyptian agricultural policies concerning labour, mechanisation, and output prices. The results show that Egypt's agricultural policies of taxing output and subsidising certain inputs have hada substantial negative impact on agricultural productivity. 相似文献

This article identifies four historical phases of relations between Islam and the Western world, as led by the United States. The first phase was a convergence of values coinciding with a divergence of empathy. The second phase reversed the order – Islamic and Western values diverged, but intercommunal relations became closer. The third phase is after September 11 when intercommunal relations once again diverged while differences between Western and Islamic values were greater than ever. The futuristic fourth phase of Islam's relations with the U.S.‐led Western world is when the power of the new American Empire is circumscribed, Western values become less libertarian, and Islam reconciles itself to modernity. 相似文献
